ARTIFICIAL FUEL.

SPECIFICATION forming part of Letters Patent No. 408,854, dated August 13, 1889.

Application filed July 31, 1888. Serial No. 281,558. (No specimens.)

To all whom it may concern:

Be it known that I, RUDOLPH J. SCHIMPER, a citizen of the United States of America, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Composition Fuel, of which the following is a full, clear, and exact specification.

My invention relates to a new and useful composition of substances whereby an artificially-prepared fuel is produced capable of yielding intense heat, and at the same time producing a pleasant and healthful atmosphere in the apartment. where used.

The object of my invention is to produce an exceedingly cheap, cleanly, portable, and compactly-pressed fuel that is suitable for all commercial, manufacturing, and domestic purposes.

My composition forming the fuel consists of the following ingredients, combined in about the proportions stated, viz: coal-dust or coal in a granular condition, fifty parts, by weight; brick-dust or calcined earthy substances of like nature, forty parts; coal-tar, pitch, or other residuum or by-product of gas-works, oil-distilleries, or asphaltum, resinous distillates, or other hydrocarbons in a sessing similar antiseptic and fragrant elements.

The before-mentioned ingredients of coal and brick are to be reduced to either a granular or powdered condition and then thoroughly mixed with the pitch, tar, or other substances by agitation in any suitable pug-mill, having heat furnished to said mixture by means of exhaust or live steam injected into the agitating apparatus while in motion, or by heating the said agitator and its contents by constructing the agitating apparatus with a jacket, and into and around which either steam or hot water is allowed to circulate or pass.

The coal-dust and granulated or powdered brick, when mixed with the hydrocarbon substances before named, become extremely hard, and thus permit the blocks to be transported without breakage, and the quantities of each ingredient may be varied to suit the uses to which it is to be applied without departing from the principle and nature of my invention.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is-

lhe herein-described composition of matter designed or intended for fuel, the same consisting of granulated brick, coal-dust, and pitch, tar, or other analogous residuum, the whole mixed, in substantially the proportions specified, and compressed, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 38th day of July, 1888.

RUDOLPH J. SCHIMPER.
